Could Fetuin-A Be a Biomarker for Autism Spectrum Disorder and Cognitive Developmental Delay?

Early detection of cognitive developmental delay (CDD) and autism spectrum disorder (ASD) is challenging, despite the numerous scientific studies conducted and different therapeutic strategies. Lack of a biomarker for autism is a limiting factor for early diagnosis, which could provide better outcome with early start of therapy. Because of the high serum fetuin-A concentration during intrauterine life, it has been suggested that fetuin-A may have a role in brain development. The current study sought to determine if fetuin-A, a multifunctional glycoprotein thought to have a role in brain development, may be used as a biomarker for the diagnosis of ASD and developmental delay. The study involved 55 children with cognitive developmental delays and 40 healthy children. Two categories of children with cognitive developmental delays were identified. The participants were subjected to a psychiatric assessment as well as developmental testing. Only 54.5% of the 55 individuals had CDD, whereas 45.5% had ASD. Using an ELISA kit, the levels of serum fetuin-A were determined spectrophotometrically. The serum fetuin-A levels in the patients from the test group were found to be significantly lower than in the healthy individuals (p < 0.001). The cutoff value for the serum fetuin-A levels for cognitive developmental delay and autism spectrum disorder was 518 µg/liter, according to the results of ROC analysis (84.6% sensitivity and 91.4% specificity, AUC: 0.95, p < 0.001). The findings suggest that the serum fetuin-A level may be used to diagnose autism spectrum disorder and cognitive developmental delays.

Online challenges that emerge as a public health issue for adolescents: Assessment of psychiatric comorbidity and the importance of parenting

ABSTRACT Background: Online Challenge is neither an application nor an internet-based game; instead, users receive a link to it via chat groups on social media. Our aim is to identify the potential differences between the normal population and youth drawn to online challenges. These potential differences are the examining the parenting skills of parents of children who participate in the challenges and determining underlying psychopathologies through structured clinical interviews. Method: A questionnaire-based cross-sectional study was used to obtain further in-depth information on the comorbid psychopathology of children who play the BWC and on the parenting skills. The Development and Well Being Assessment and Alabama Parenting Questionnaire was applied to the children and their families in both the control and case groups. Results: Two groups of children and parents were recruited: a clinical sample (case) group (n = 34) and a community sample (control) group (n = 141). Attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), specific phobia and CD (conduct disorder) were significantly more frequent in the clinical sample than in the community sample. The median scores for the Alabama Parenting Questionnaire (APQ) parental involvement, positive parenting, and poor monitoring/supervision subscales were significantly lower in the clinical sample than in the community sample. Conclusion: As far as we know, this study is the first to examine comorbid psychopathologies of online challenge-style games and parenting skills. We believe that as research into these subject increases, it will assist mental health professionals to develop prevention strategies and to manage cases resulting from the Blue Whale Challenge (BWC) and other online challenges that pose a serious threat to mental health and that have driven many young people to suicide worldwide.
